.2 Claims. (01. 101-226) My invention relates to means forinstantaneously imprinting upon a suitable receiving stock, such aspaper or comparable wrapping material, an indicium or legend,particularly an advertisement of the user of the device.

An object of my invention is to provide an inexpensive and infalliblemeans for imprinting an advertising legend on wrapping paper beingdispensed.

Another object of my invention is to provide means generally useful in astore, for imprinting a selected legend upon wrapping material such aspaper or bags.

A further object of my invention is in general to improve imprintingmechanisms.

The foregoing and other objects are attained in the embodiment of theinvention disclosed in the drawing, in which-- Fig. 1 is a sideelevation of an imprinter in accordance with my invention, aside of thehousing being removed to disclose the interior;

Fig. 2 is a front elevation of my imprinter, a part of the housing beingbroken away to disclose the interior; I

Fig. 3 is a fragmentary cross-section transversely of the rolls, showingpaper passing through the intermeshing portions of the rolls.

In its preferred form, the imprinting device of my invention includes ahousing within which is disposed a plurality of rollers havingcorrugated portions so that they all are rotated together under theinfluence of withdrawal of a paper being imprinted, taken from a rollwithin the casing and passing between a pair of rollers one of whichcontains a die periodically brought into contact with an inkingmechanism and with the paper so that thepaper as it passes between therollers is periodically imprinted, the imprinted paper being severablefrom the remaining paper on the roll by tearing against an edge of theenclosing housing.

Although the imprinting mechanism of my in vention is susceptible of agreat deal of variation, depending upon the particular environment inwhich it is utilized, and depending further upon the individualrequirements of special papers, wrapping materials, and the like, it hasbeen successfully embodied in the form disclosed in the drawing, inwhich there is preferably afforded a support 6 which conveniently can bea counter or table within a store at a convenient location. The entiremechanism is preferably included with an attractive enclosing housing 1preferably. fabricated of metal and readily removable to disclose theinterior. Within the housing I preferably provide a pair of uprights 8each of which is secured to the base 6 by fastenmgs piercing anoutturned foot |2 thereon; The distance between the uprights 8 ispreferably variable by moving the fastenings H to accommodate rolls ofpaper of different widths. Each of the uprights at a convenient point initsheight is provided with a bearing slot |3, which may be supplementedby a set-screw, and carries an eX- tended shaft IS on which a paper rollI1 is mounted. By suitable manipulation the paperroll l1 may be removedand. replaced. In advance of the uprights 8 I preferably provide anotherpair of uprights 2|, which are subfor securing it on the table or base6. At their upper ends all uprights carry an outturnedvflange 26 throughwhich fastenings 21 pass to engage a top strap 28 having therein aplurality of apertures 29 so that the uprights 8 and 2| are firmly heldin any of several differently spaced positions. Mounted in extensions 3|from the uprights 2| are ball bearings or other suitable antifrictionbearing members 32 in which a guide roller 33 is mounted, so that apaper sheet 34 extending tangentially from the roll I1 is passed underthe guide roller 33 and is established at a fixed horizontal locationdespite variations in diameter of the roll 1 1 as the paper is utilized.

Journaled in the uprights 2| is a feed roller 36 mounted on an extendedshaft 31 which at opposite ends is disposed in anti-friction or ballbearings 38 inhibited against removal but vertically adjustable by meansof set-screws 39 in the uprights, so that the roller 36 rotates freelyin a selected position. This roller is supplemented by a similar roller4| mounted on an e tended shaft 42 likewise disposed in anti-frictionball bearings 43 restrained against removal by set-screw 44 in theuprights. Adjacent its end the roller 4|, which is fabricated of rubberor similar yielding material, is provided with a sponge or cushionrubber portion or with corrugations 46 comparable to small gear teeth,which interengage and virtually intermesh with comparable corrugations4'! on the similarly fabricated roller 36. The sheet of paper 34 ispassed between the rollers" 36 and 4| so that, as the sheet is withdrawnfrom the roll H, the rollers 36 and 4| are rotated in accordance withthe surface speed of the paper, the intermeshing corrugations spongerubber, making the rollers turn substantially in unison.

In accordance with my invention, I provide means for imprinting upon thepaper sheet 34 as it is withdrawn, and correspondingly interrupt themid-portion of the roller 4| to provide a printing die 49 thereupon.This die 49 may take the form of a removable, rigid metallic plate heldby fastenings to the roller 4|, or can be a yielding plate of rubber orcomparable material formed integrally with the roller. The die revolveswith the roller 4| and during its revolution is inked by contact with aninking roller 52 which occupies H the central portion of an extendedshaft 53. The

inking roller 52 can either be a surface inking de'-- vice or have anink reservoir Within itself, but in either event is effective to ink theface of the die 49 during rotation thereof and carries corrugated; orsponge rubber portions 54 which interengage with the corrugated orsponge rubber portions 2!, being adjustably retained therein bysetscrews 51 and 58 so that it can be moved into appropriate inkingcontact with the die roller. Due to the interengagement of the inkingroller and the die roller, withdrawal of the paper sheet 34 keeps theinking roller in suitable actuation so that ink is evenly spread, andthe diameter of the inking roller is somewhat smaller than that of thedie roller so that a thorough distribution of ink is effected.

The paper which has passed through the rollers 36 and 4|, having beensuitably imprinted, passes out of the housing 1 through an elongatedslot 6| in the face thereof, which is partially defined by a lowertrough 62 to act as a backing or stop for the paper when the operatorsfingers reach into the trough to grasp the imprinted sheet.

The slot is likewise partially defined by an upper tearing edge 63 whichis preferably somewhat ping paper which is purchased at the standardrate, since it is originally plain and not imprinted, yet to have awrapper bearing an advertisement or other suitable imprint. Furthermore,it is entirely possible, by reverse rotation of the roll IT, to withdrawthe sheet 34 from between the driving rolls and, by the installation ofa hand crank thereupon, to feed paper bags or other individual sheets ofwrapping material through the rolls in order that they may beindividually imprinted.

"The transverse or lateral adjustment of the device can be varied fromtime to time in accordance with major or minor variations in the widthof the paper rollbeing utilized, the extended shafts facilitatingthisadjustment effected by the use'of selected ones of the numerousapertures 29.

' I claim:

1. A paper imprinter comprising, a frame, a support rotatably journaledon said frame to receive a paper roll, a pair of imprinting rollersjournaled on said frame, a printing die incorporated on one of saidrollers, the paper being adapted to be'unrolled and drawn in a pathbetween said rollers while being imprinted by said die, and intermeshingcorrugated portions of resilient rubber on adjacent ends of said rollerswithin said path, said corrugated portions being comparable to smallgear teeth whereby the rollers turn in unison.

2. A paper imprinter comprising, a frame, a support rotatably journaledon said frame to.- receive a paper roll, a pair of imprinting rollersjournaled on said frame, a printing die incorporated on one of 'saidrollers, the paper being adapted to be unrolled and drawn. in a pathbetween said rollers while being imprinted by said die, intermeshingcorrugated portions 'of resilient rubber on adjacent ends of saidrollers within said path, an inking roller journaled'on' said frame forengagement with the die of said die incorporated roller and having acorrugated end portion interengaging said corrugated portion of said dieincorporated roller, the said corrugated portions being comparable tosmall gear teeth whereby the rollers turn in unison.
